What does sinus rhythm anterolateral st elevation early repolarization means? age 22

Ecg: Early repolarization is a variant of normal found in some people. It is not a reason for concern.

Probably normal: At your age there are often some changes in the cardio gram caused by being young and thin. The waveforms in some leads can look like there is a problem, but at your age these changes are considered normal. Ask your doctor to explain in more detail if you have further questions. Good luck!

Normal variant: a simple test such as a stress echo would confirm but most likely its just your normal baseline.
